  • Multi-functional differential cascode voltage switch logic
    Patent number: 4686392
    Abstract: A differential cascode voltage switch (DCVS) logic circuit in which different DCVS logic blocks are connected in parallel to the output lines. Selection transistors connected to each logic block complete the conductivity path to ground. Only one selection transistor is selected at a time to thereby select the associated logic blocks. The circuit can be improved by merging portions of the different logic blocks which are identically connected to the output lines.
